Background:The frequency of eosinophilic oesophagitis (EoE) occurrence is escalating. Current diagnostic criteria recently proposed for the disease, determine that previous estimates of incidence and prevalence are outdated.Aim: To gauge the current incidence and prevalence of EoE by performing a systematic review of population-based studies.Methods: Three electronic databases were searched from their inception dates to September 2018. A total of 2386 documents were screened; 29 studies reported on the prevalence and incidence of EoE in the general population.
Results:The pooled prevalence of EoE was 34.4 cases per 100 000 inhabitants (95% CI, 23.1-47.5), and was higher for adults (42.2; 95% CI, 31.1-55) than for children (34; 95% CI, 22.3-49.2). The pooled EoE incidence rates were 6.6/100 000 person-years (95% CI, 3-11.7) in children and 7.7/100 000 (95% CI, 1.8-17.8) in adults.No differences were found between North American and European studies using varied sources of data (insurance and administrative databases compared to hospital-bases case series). Subgroup analysis according to risk of bias did not change results significantly. A steady rise in EoE incidence and prevalence rates was observed over time, comparing studies conducted under subsequent definitions for EoE. No significant publication bias was found.
Conclusions:In a systematic review and meta-analysis, we found a sharp increase, higher than previous estimates, in the incidence and prevalence of EoE in population based studies. Results from studies carried out in developed countries show broad consistency and provide evidence of increasing pooled prevalence and incidence of EoE rates over time.Additional supporting information will be found online in the Supporting Information section at the end of the article.How to cite this article: Navarro P, Arias Á, Arias-González L, Laserna-Mendieta EJ, Ruiz-Ponce M, Lucendo AJ.

This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e161. Learning Objective-Upon completion of this activity, successful learners will be able to list the main alternatives for the treatment of patients with eosinophilic esophagitis; list the expected response rates for each of these alternatives; and be able to select effectively the most suitable treatment option for patients with eosinophilic esophagitis based on their clinical characteristics.
Our results show that the metabolic disturbances associated with RA depend on the degree of inflammation and identify inflammation of adipose tissue as the initial target leading to IR and the associated molecular disorders of carbohydrate and lipid homeostasis. Thus, we anticipate that therapeutic strategies based on tighter control of inflammation and flares could provide promising approaches to normalize and/or prevent metabolic alterations associated with RA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
